Application filed December 17, 1968. Serial No. 467,92?. i

To all whom it may concern:

Be it known that I, CALEB E. SHREVE, a citizen of the United States, and a resident of Atlantic City, State of New Jersey, have invented certain new and useful Improvements in Milk-Fails, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, forming a part of this specification.

The main objects of this invention are to provide a sanitary milk pail of simple construction, that may be conveniently adjusted to receive the milk during the operation of milking, and that will prevent the milk from being contaminated by foreign matter or by the absorption of unpleasant or unwholesome odors; to provide a sanitary milk pail that may be conveniently taken apart for cleaning; and to provide other improvements as will appear hereinafter.

in the accompanying drawings Figure 1 is a side elevation partly in vertical section of a milk pail constructed in accordance with this invention; Fig. 2 a side elevation of a portion of the same; Fig. 8 a perspective of a portion of the same; Fig. 4 a front elevation of the upper portion of the pail; Figs. 5 and 6 are a side elevation and a fragmentary vertical section respectively of a strainer forming part of the pail; Fig. 7 an enlarged fragmentary vertical section of the strainer; Fig. 8, a fragmentary perspective view of a portion of the same; and Fig. 9 a top plan View of a portion of the same.

Referring to the drawings, the pail is provided with a hollow body portion 1 preferably in the form of an inverted truncated cone, having' a cover 2 fixed thereon, the cover being provided with a handle 3 rigid therewith, whereby the pail may be carried. Upon one side of the pail and extending upwardly and outwardly from the cover is an inclined cylindrical tubular spout, the lower end of which is rigidly connected to the cover and registers with an opening 5 provided therefor in the cover through which the spout communicates with the interior of the body of the pail. The upper edge of this spout l projects outwardly beyond the outer periphery of the body of the pail and is provided with a bead 6 for stiffening the spout.

rTelescoping within the spout 4 is a tubular member 7, which also is provided at its upper edge with a bead 8 for stilfening the same. The tubular member 7 is freely movable longitudinally and rotatably in the spout d and is held in any desired fixed position by means of a wedge 9 which lits, 1n a downwardly tapering pocket provided therefor in the inner surface of the spout contiguous to the upper edge thereof be* tween the spout and the tubular member 7 Fitting snugly within the upper edge or mouth of the adjustable tubular member 7 is a strainer 10, comprising a conical body portion or vessel 11 tapering downwardly, and terminating at its lower end in a threaded aperture 12, which is closed by a threaded cap 13. The interior of the strainer communicates with the interior of the telescoping tubular member through an aperture 15, in the upper side of the body portion of the strainer, the aperture being covered with straining material 16, such as wire mesh, or a perforated plate, or other foraminous material. To prevent the streams of milk from passing directly through this screened opening 15 of the strainer, a shield 14 is arranged concentric with the strainer in front of and spaced from the foraminous cover 16, the space between the cover and the shield being closed at its upper side and at its ends but opening downwardly into communication with the body of the strainer. The shield 14 is provided with a laterally extending ear 14 projecting from each end thereof. These ears 111 are slidingly and removably supported by upwardly extending brackets 15 the lower ends of which are iixed to the side of the strainer. The shield let may thus be removed from the strainer for cleaning purposes by lifting the shield out of engagement with the brackets. Apertures 16 are provided in one end of the shield adjacent its upper edge to allow the air to pass out from the space under the shield and from the body of the pail as the milk flows .in under the lower edges of the shield.

llithin the strainer and between the aperture 15 in the side thereof and the bottom of the strainer is a removable perforated plate 17, which rests upon brackets 18, rigid with the body of the strainer and forms a partition between the upper andlower portions of the strainer. rIhis partition acts as a screen to permit any foreign matter in the milk to sift through it and to be retained in the chamber 19, formed by the screen in the lower parts of the strainer, from which the foreign matter may be removed from time to time by inverting said strainer, or by removing the cap 13, which closes the lower end of the strainer.

The strainer is held removably in a fixed position in the telescoping member 7 by means of a pair of downwardly extending catches 20, which are arranged upon opposite sides respectively of the body of the strainer, the upper ends of the catches being rigidly secured to the body of the strainer by means of rivets 21, or otherwise and the lower end of each catch being provided with a transverse recess 23, adapted to engage with a pin 22 fixed upon the telescoping member 7 and extending laterally therefrom. The recesses 23 open in the same direction rotatably so that the catches may be disengaged from the pins 22 by rotating the strainer with respect to the pins. Pins 25 are also provided adjacent the upper edge of the fixed spout 4, projecting outwardly therefrom, and adapted to be engaged by the catches 2O of the strainer, whereby when pre ferred the telescoping member 7 may be removed and the strainer connected directly in the fixed spout.

The upper portion of the strainer 1() is enlarged to form an upwardly facing internal annular shoulder 30, surrounded by an upwardly projecting cylindrical rim 3l, having an outwardly beaded edge 32 for stiffening the same. The rim 31 and shoulder 30 together forni a socket for the reception of the lower end of a hood 35, which fits snugly therein.

The hood 35 is in the form of a curved elbow which communicates through its inner end with the upper end of the strainer and which opens outwardly through the aperture 36 in its outer end, which faces obliquely downward, the remainder of the hood being closed. The purpose of the hood is to prevent any foreign matter froin falling vertically iiito the strainer, but to permit of the introduction of the rmilk during the milking operation through the inclined open outer end of the hood.

For the purpose of enabling easy observation of the milking operation the upper portion of the hood 35, is provided with a rectangular opening 37 surrounded by an outwardly projecting rectangular casing 3S rigid with the hood, the opening being covered by a substantially horizontal pane of glass 39 or other suitable transparent material.

rIhe hood is detachably connected to the strainer by means of a pair of downwardly depending catches 40, the upper ends of which are fastened by means of rivets 41 to the hood, the lower end of each catch being provided with a lateral recess 42, adapted to engage over a pin 43, )rejecting rigidly from the upper portion of the strainer. The recesses 43 of the catches face in the same direction rotatably so that the hood may be disengaged from the strainer by rotating the hood with respectto the pins.,

In using this improved milk pail, the telescoping tubular member 7'is adjusted in the spout by means of the wedge 9to bring the inlet aperture 3G of the hood into convenient position to receive the milk from the animal. it is to be noted that the hood projects beyond or overhangs the outer periphery of the body of the pail so that the body of the pail does not have to be placed directly under the animal where it would be in danger of being upset, but. may be located at one side of the animal.. V he streams of milk are directed by the operator through the opening 36 into the hood and the first portion of the milk thus introduced falls through the perforated plate 17 and into the bottom compartment 19 of the strainer and as the operation proceeds the plate gradually submerged and the milk above the yplates overflows through the screened aperture 15 and through the telescoping 'tubular member 7 and spout 4 into the body of the pail. Any foreign matter ieavier than milk entrained by the milk settles through the perforated plate and may be removed as previouslT explained. The perforated plate 17 over the compartment 19 protects the` .milk in the compartment from being agitated by the incoming streams and facilitates the precipitation of any foreign matter.

The screened aperture 15 in the strainer is preferably strainer opposite the entrance 36 to the hood where it will be nearest the streams of milk as they fail into the strainer to facilitate the speedy movement of the milk from the st rainer into the body of the pail; but the aperture 15 and its shield 14 could be placed in any other position in the side of the strainer' above plate 17 without detracting seriously from the efficiency of the strainer.

Then it is desired to empty the pail, the telescoping member 7 is removed together with the hood and strainer and the contents of the pail may then be poured out through the spout 4, after which every part of the pail may be conveniently cleaned and kept in a sanitary condition.

In addition to the advantages heretofore mentioned, a further and important advantage of the improved milk pail is that the inlet into the pail through the hood facing downwardly the operator may conveniently, and moreover is required to, direct the streams of milk laterally into the inlet by a movement of the hands laterally, away from the animal being milked, which is a` more natural method than the method in which the pressure is applied vertically.

Although I have described only the preferred forni in which this invention may be located upon the side of the embodied, yet 1 do not limit myself to this particular form, as various changes might be made in the construction herein set forth, without departing from the spiritof this invention or the scope of the appended claims.
